That is very simple. First, ensure that the option "Enable customizable menu shortcuts" is enabled on the "Other" preferences page, then, suppose you want to assign a shortcut key to a function, e.g. sending all mail out should start when you press Ctrl-Y. Click the "Message" menu and move the mouse over "Send all messages" (or press Alt+M to unroll the "Message" menu then use the down cursor key to activate this "Send all messages" menu entry). Now you press Ctrl-Y. Immediately the menu text is updated and the function is in place. Please note that a previous function that Ctrl-Y was assigned to, will no longer have a shortcut key. If you want to remove the key binding, do the same thing, but press the "delete" key on the menu-item. Then the key binding is removed.

If you are not interested in the subject of a thread you won't be bothered with the mails anymore.

IGNORE THREAD flag can be also checked in Condition of filtering or processing with 'ignore_thread' keyword.

Why doesn't colour labelling work under KDE?

It seems that KDE likes to apply its own color schemes to GTK applications.
Try changing/editing/replacing its configuration file ~/.kde/share/config/gtkrc to get better coloring.

KDE likes to map its gui style stettings from QT (on which KDE is built) to GTK (on which GNOME is built). Creating an empty file called ~/.no-qtrc-to-gtkrc-mapping in your home directory stops this. You will need to restart the KDE session for this to take effect.

I had the same problem (running kubuntu 5.10-preview), and to get claws-mail (version 1.9.14) to display the new blue color in the folder view again, the steps described above didn't do it for me. I had to also change one option in the KDE Settings in KDE -> Settings -> Appearances -> GTK Styles and Fonts. Here i had to switch to "use another style: Raleigh". With that it is working. I think this is really a KDE bug, because in the settings tab colors I unchecked the "Apply colors to non-kde-applications" checkbox and it is still doing it for claws-mail. (Markus.Kalb@gmail.com)

How can I remove mailing list information from Subject headers?

Very often, when you are subscribed to a mailing list, you will store each message from that list in a folder dedicated to that list, (this is actually recommended since Claws provides great mailing list handling). Very often too, mailing lists include some words in the Subject header to identify the messages, for instance "[cairo]". These additions do not provide useful info if you have organized your folders as described, but Claws allows you to simplify the displayed Subject by setting the folder property "Simplify Subject Regexp". It is a regular expression that matches the part of the Subjects that you want to remove. In our example you would set it to

\[cairo\]

This property also affects the way messages are threaded when you have also set the preference "Thread using subject in addition to standard headers".

How do I copy my mail archive to another machine?

You need to copy the .claws-mail directory and your entire local mail archive. Make sure that the timestamps of all the files are preserved or else metadata (read/unread messages, color coding, etc.) might get lost. To preserve the timestamps, use tar, rsync, or unison (with the -times) option.
